build: update ng-dev config to work with Node.js 18.16

Update the ng-dev configuration to be compatible with Node.js 18.16. This adjustment eliminates the necessity for ts-node, which is crucial due to compatibility issues between the current tsnode esm version and the latest ESM loaders. For more details, refer to: TypeStrong/ts-node#2094
